Application April 7, 1

This invention relates to improvements in straight sided stacking tote or packing boxes.

The main objects of this invention are:

First, to provide a straight sided tote or packing box which is light in weight and at the same time is capable of carrying heavy loads and withstanding severe usage. ,Second, to provide a stacking box having these advantages which provides a reenforcing upper edge or rounded rim formed of sheet metal which is not likely to injure an operator or abrade or tear objects which may be contacted therewith or slid over the same.

Third, to provide a structure having these advantages which may be economically produced and easily kept in a sanitary condition even though repeatedly used.

Objects relating to details and economies of the invention will appear from the description to follow. The invention is defined and pointed out in the claims.

A preferred embodiment of the invention is illustrated in the accompanying drawing, in which:

Fig. l is a perspective view of a straight sided tote or packing box embodying my invention.

Fig. 2 is an enlarged fragmentary perspective view, parts being broken away and in section to show structural details.

Fig. 3 is a fragmentary vertical section illustrating fragments of a pair of the boxes in stacked relation.

The box of my invention is desirable for many uses. baked goods and other merchandise which commonly necessitates the use of a plurality of boxes.

The embodiment of my invention illustrated comprises side walls I and end walls .2 preferably formed of fiber board. The bottom 3 is formed of sheet metal and has downwardly projecting flanges 4 at its edges fitting within and secured to the inner sides of the side and end walls as by means of the rivets 5. The lower edges of the bottom flanges are preferably flush with the lower edges of the walls and constitute reenforcing members for the side walls, the bottom and its flanges preventing buckling of the lower portions of the walls either inwardly or outwardly.

The adjacent ends of'the side and end walls are secured together by the angled corner pieces 6 fitting thereover and secured thereto as by the rivets 1. These corner pieces are desirablyof fiber board, although they may be of metal if desired. In addition to securing the adjacent ends of the wall together, they serve as wear members for the corners and conceal the wall joints. The walls are provided with side and end rim members 8 and 9 formed of sheet metal conformed to angle section and disposed with the angles facing inwardly and downwardly. The vertical legs ll! of these members are lapped upon the outer sides It is particularly desirable for handling 950, Serial No. 154,666

5 Claims. (01. 2204) of the side and end walls and secured thereto as by 'rivets ll. The horizontal legs I2 of the rim members extend inwardly over the upperedges of the walls and terminate in reversely bent flanges l3... These flanges are connected by the angled corner irons l4 inserted within the folds and secured thereto desirably by spot welding as indicated at l5.

The corner pieces 6 are secured to the rim members by rivets I passing therethrough and through the walls, and they are also secured to the downturned bottom flanges, by rivets I so that the corner pieces 6 constitute tie members for the bottom and the rim. The rim members provide upwardly facing shoulders l2 constituting supports for a superimposed box as shown in Fig. 3 with the upwardly projecting rim flanges within the recessed bottom. This maintains the boxes in stacked relation.

.The load of the superimposed boxes is effectively supported bythe lower box, the parts of the box being arranged so that, even when .formed of light material, they are capable of withstanding heavy superimposed loads. y

The end walls in the embodiment illustrated are provided with hand openings l6 and with grip members I! desirably .formed of sheet metal folded to provide a tubular grip and an upwardly projecting attaching flange l8 disposed within the vertical legs of the end rim members and secured thereto by rivets l9 passing through the end walls. The grip members extend substantially beyond the hand openings and constitute reenforcing members for the end walls. The grips abutthe lower edges of the rim members so that the load is effectively distributed.

The corners of the bottom are desirably beveled 'or cutaway as at 20 to provide ventilation and drain openings, as it is desirable to wash the boxes and, also ventilation is desirable for some The bottoms are reen'forced by I have illustrated and described my invention in a highly practical embodiment thereof. I have not attempted to illustrate or describe other adaptations or embodiments which I contemplate, as I believe this disclosure will enable those skilled in the art to embody or adapt my invention' as may be desired. Further, it will be'understood that I have used the term, side and end" wall, in the specification and claims/for 'c'onvenience in description. While the box illustrated is elongated, my invention is equally well adapted to square boxes and boxes of other shapes and relative dimensions." 7

Having thus described my invention, whatI claim as new and desire to secure by Letters Patent is:
